RHEL 6 / 7 : Storage Server (RHSA-2016:1494)

Medium Nessus Plugin ID 92603

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An update for samba is now available for Red Hat Gluster Storage 3.1 for RHEL 6 and Red Hat Gluster Storage 3.1 for RHEL 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Samba is an open source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.

Security Fix(es) :

* A flaw was found in the way Samba initiated signed DCE/RPC connections. A man-in-the-middle attacker could use this flaw to downgrade the connection to not use signing and therefore impersonate the server. (CVE-2016-2119)

Red Hat would like to thank the Samba project for reporting this issue. Upstream acknowledges Stefan Metzmacher as the original reporter.

Solution

Update the affected packages.
